Chikuma River Wine Valley
千曲川ワインバレー
Nagano's biggest, fastest-growing boutique wine valley
The Chikuma River Wine Valley (千曲川ワインバレー) is one of Nagano Prefecture's four officially designated wine valleys under the Shinshu Wine Valley Initiative (信州ワインバレー構想), and by area it is the largest of the four. Stretching roughly 100km along the Chikuma River from Komoro in the south to Nakano in the north, it spans about twelve municipalities including Ueda, Komoro, Chikuma, Tomi, Tateshina, Aoki, Nagawa, Sakaki, Nagano, and Nakano. Low rainfall, long sunshine hours, well-drained soils, and pronounced diurnal temperature swings make it one of Japan's most promising terroirs for European grape varieties such as Merlot, Chardonnay, Cabernet Sauvignon, Sauvignon Blanc, and Pinot Noir. Much of the valley's rapid growth traces back to essayist Toyoo Tamamura, who opened Villa d'Est Garden Farm & Winery in Tomi in 2003, and to the Chikuma River Wine Academy (千曲川ワインアカデミー), founded in 2015 with winemaker Koshi Konishi, which has trained a new generation of independent winemakers who went on to open dozens of small, terroir-driven boutique wineries across the valley. Older estates such as Obuse Winery (founded 1942) and Manns Wines Komoro Winery (1969) sit alongside this new wave, making Chikuma River Wine Valley one of the most dynamic and fastest-growing wine regions in Japan today.

Il Fait Beau
Il Fait Beau is Chikuma City's first winery, founded in 2022 by Yoshiharu Ochiai — who runs an elder-care facility and set out to revive the region's abandoned vineyards after training at the Chikumagawa Wine Academy. Winemaker Hiroko Kitayama crafts the wines from grapes grown across four estate vineyards at elevations between 400m and 800m on both banks of the Chikuma River, planted with varieties including Chardonnay, Chenin Blanc, Sauvignon Blanc, Merlot, Cabernet Sauvignon, Cabernet Franc, Syrah, Malbec, and Pinot Noir. The winery has grown its own grapes since 2016 and opened its in-house winemaking facility in August 2022, producing wines made from 100% Chikuma-grown fruit that express the terroir of the region.

Nishiiida Shuzoten
Founded in the late Edo period in Shinonoi, Nagano City, Nishiiida Shuzoten is a historic sake brewery best known for its sake brand 'Sekizen'. Since the 8th-generation owner's era, it has also produced wine and cider using flower yeast developed with Tokyo University of Agriculture — the only winery in Nagano Prefecture to do so, with over 40 years of flower-yeast winemaking history. Its signature 'Shinshu Local Wine Mellows' is a dry white made from Niagara grapes grown in its own small vineyard, fermented with day-lily flower yeast, alongside a cider made from local Shinano Gold apples. The winery sits in the northern district of the Chikuma River Wine Valley.

Takayashiro Farm & Winery
Founded by a group of local farming families in Nakano City, Nagano Prefecture, Takayashiro Farm & Winery grew out of an existing fruit-growing operation — apples, table grapes, and peaches — before planting its first wine grapes, Cabernet Sauvignon, in 1998. Today the estate farms roughly 6 hectares on the cool, elevated slopes of Mt. Takayashiro (around 400m), growing more than a dozen varieties including Chardonnay, Kerner, Riesling, Viognier, Sauvignon Blanc, Pinot Gris, Merlot, Cabernet Sauvignon, Cabernet Franc, Pinot Noir, and Zweigelt. Led by president Ko Takehada — a former Suntory sales employee turned grower — the winery produces around 20 different wines and 35,000 bottles a year, alongside cider, apple juice, and jam, and prices many of its wines affordably (from around ¥1,500) to keep them within reach of the local community it was built to serve.

UTABI Winery
UTABI Winery is the first winery established within Nagano City, located in the Utabi area of the Shinonoi district. Founded in 2024 by Kei Tanaka, a Sommelier Excellence titleholder and GI examination judge who returned to his hometown after working as a sommelier at renowned hotels and wine bars in Karuizawa, Tokyo, and Kyoto, together with Motohiro Takizawa, who trained at an established Japanese winery. Tanaka spent five years searching for the ideal vineyard site before settling on Utabi, where marine sediment soil dating back to the Jurassic period, favorable sun exposure, and good airflow across two plots at 650m and 730m elevation create conditions well suited to fine wine grapes. The winery's guiding philosophy is uncompromising winemaking that lets the grapes' natural character speak for itself, informed by Tanaka's training across multiple wineries in Nagano and Hokkaido, including strict-hygiene techniques learned from producers who ferment with wild yeast and no added sulfites. UTABI Winery is part of the Chikuma River Wine Valley and produced its first vintage in 2024, with Pinot Noir and Chardonnay as its flagship varieties, aiming for roughly 15,000 bottles annually at full capacity.
